Rupp Threaded Antenna Support w/6" Flat Mount, Oval 4-Way Base & 1.5" Collar

The Rupp Threaded Antenna Support with 6" Flat Mount, Oval 4-Way Base & 1.5" Collar is a precision-engineered mounting solution designed for marine antenna systems requiring robust, reliable installation. Built from forged and anodized aluminum, this antenna support combines structural strength with corrosion resistance—critical factors for saltwater and extended outdoor environments where standard mounts fail prematurely.

The oval four-way base provides multi-directional mounting flexibility, while the threaded design with 1.5" collar allows secure fastening to tuna tower tops, hardtops, or other elevated platforms common on commercial and recreational vessels. The locking collar holds the antenna firmly in place during operation, yet unlocks conveniently for lowering when needed—a practical feature for docking, bridge clearance, or service access. The 6" flat mount provides a stable footprint that distributes load evenly across the mounting surface, reducing stress concentration that can lead to galvanic corrosion or structural fatigue over time.

This mount is engineered for marine operators who demand durability under demanding conditions. Whether supporting VHF, SSB, or navigation antennas on offshore fishing boats, research vessels, or commercial maritime operations, the anodized aluminum construction resists oxidation and maintains dimensional stability across temperature swings. The threaded configuration is preferred over welded or adhesive mounts because it allows field replacement without permanent modification to the structure.

Rupp Marine's antenna mounting systems are recognized in the marine industry for balancing functional design with aesthetic finish. This model integrates into existing rigging systems without requiring custom fabrication, reducing installation complexity and cost.
